SKU CH-6XAH-BV661

Adds two RS232 serial ports and one parallel LPT port via a single PCIe slot using the AX99100 chip for reliable legacy device connectivity

  • Adds two RS232 COM ports and one DB25 LPT port via a single PCIe slot
  • AX99100 controller chip ensures stable long-term data transmission for industrial use
  • Connects legacy parallel printers through the DB25 LPT interface on modern motherboards
  • Works with Windows and Linux for office and industrial equipment installation
  • Standard-height bracket fits regular desktop chassis with plug-and-play driver support

PCIe card adds RS232 and LPT ports

The SMUGDESK AX99100 adapter fits a single PCI Express slot and provides two independent RS232 COM ports plus one DB25 parallel port. It targets technicians and businesses that must connect legacy serial controllers, point-of-sale hardware or older parallel printers to modern motherboards lacking native DB9 and DB25 connectors.

AX99100 chip controls all three ports

The on-board AX99100 controller manages the two RS232 channels and the LPT interface simultaneously, delivering stable long-term data transmission. Driver packages for Windows and Linux enable plug-and-play installation so the card is recognised without manual configuration in office or industrial environments.

Passive design draws minimal slot power

No active cooling is present, so the card runs silently and adds negligible load to the PCIe power budget. The standard-height bracket fits regular desktop chassis, and the absence of fans eliminates moving-part wear during continuous operation with industrial equipment or legacy printers.
